Mellow Mushroom Cottleville - The Story

Inspired by the aesthetic of the 1980’s, our restaurant celebrates all things Cottleville and Missouri. The 80’s inspiration started with the Delorean, a vehicle that the owner Tammi Hilton’s father drove for many years, because of this, there is a large mural of a Delorean with a license plate reading “88 MPH”. Eye-catching exterior murals were painted by local artists Daniel Burnette and Peat “The Eyez Guy” Wollager. The colorful interior murals were created by artist Ruben Ubiera.

Customer Reviews

Excellent food, excellent staff, and the sauce was delicious without being spicy for me(I'm a spice wimp). Our waiter kept us advised of our wait time left regularly and checked on us frequently. They have an excellent selection for vegans as well as having quite a wide selection of drinks. Fantastic experience, highly recommend!!

This place was a total vibe. Loved the chill atmosphere here. Our waitress was wonderful and did an excellent job of providing us with recommendations of things to try. Loved our pizza and the portobello mushroom appetizer. We will definitely be back!

There was no wait when we went at 1:00pm. Staff is so nice and helpful. The atmosphere is full of neon vibrant colors and art. Food is delicious! They have vegan and gluten free options. We got the funky chicken bbq pizza, build your own, and pretzel bites with beer cheese. So so good and cute with comfortable vibes!

The menu is huge! I had a hard time deciding since everything sounded so good, but ended up splitting a large Mighty Meat pizza with the other two people I was with. It was more than enough for the three of us. Tons of toppings and it was delicious! It did take some time for the pizza to come out, but we were in no rush and our waitress was very friendly and checked on us frequently. Can’t wait to come back and try other items on the menu!
